Lerner, 500 W. Fulton St., Chicago, Ill. Filed Sept. 13, 1963, Ser. No. 308,804 3 Claims. (Cl. 222146) This invention relates to means for heating the contents of a container or dispenser as same is being discharged or dispensed.

One of the objects of this invention is to provide a heating unit which may be detachably secured to a conventional bottle or container for the purpose of heating that portion of the liquid or material therein which is being discharged or dispensed.

Another object of this invention is to provide an adapter detachably secured to a container or bottle of the squeeze type, which adapter includes a heat exchanger through which the material in the container or bottle passes before it is discharged, and during said passage is heated so that same is discharged in a heated state.

Another object of this invention is to provide a heating unit cooperating with a bottle or container for heating the material from the container as it passes through the heating unit.

Another object of this invention is to provide a device of the foregoing character which is inexpensive to manufacture, and which is highly efficient in operation.

Other objects will become apparent as this description progresses.

In the drawings:

FIG. 1 is a perspective view of this invention.

FIG. 2 is a sectional view taken on lines 2-2 of FIG. 1.

FIG. 3 is a View of a modified construction.

FIG. 4 is a sectional view taken on lines 44 of FIG. 3, and

FIG. 5 is a view taken on lines 5-5 of FIG. 4.

Referring to the construction shown in FIGS. 1 and 2, the container for the material or liquid contents is indicated at and has a threaded neck 12. It is preferably of the squeeze type and made of plastic material.

The adapter which is generally indicated at 14 includes a hollow housing 16 and a heat exchanger generally indicated at 18 supported therein, The housing is formed of a generally cup-shaped body 19 which is closed at the top thereof by a permanently affixed lid or cover 20. The housing has two funnel-shaped spouts 21 and 22. The funnel-shaped spouts are diametrically opposite each other and are substantially at right angles to the discharge spout indicated at 24.

Extending downwardly from the bottom of the housing is a circular sleeve 28 which is internally threaded for threaded engagement with the neck 12 of the bottle. Also depending from the bottom of the housing is a central boss 30 provided with a central bore 32 which receives and supports a pipe 34 extending into the bottle 10.

The heat exchanger generally indicated at 18 consists of a coiled pipe 36 which is supported inside said housing. One end 38 of the coiled pipe 18 is anchored in the outlet spout 24 and the opposite end 40 is supported in the bore 32 of the central boss 30. The fluid or material from the container 10 passes through pipe 34, through the 3,241,724 Patented Mar. 22, 1966 coils 36 of the heat exchanger and is discharged through the spout 24.

The housing 16 also serves as a container and is filled with hot water through either of the spouts 20 or 22 by placing same under a faucet with hot running water. The hot water can continue to flow through the container or housing by entering through one spout and discharging through the other, or, the water is allowed to remain in the housing 16. In either case the hot water will heat the coils 36 and the liquid or material in the coils and passing through the coils.

The modified construction shown in FIGS. 3, 4 and 5 is secured to the same type of bottle or container previously described. The adapter generally indicated at 39 consists of a cup-shaped body generally indicated at 48 which is formed with an inner cup-shaped member 42 and an outer cup-shaped member 44 spaced from each other and sealed at the top thereof, as at 46, to provide a passageway 48 between the side walls of the two cup-shaped members and a communicating passageway 50 between the bottom walls.

Formed between the spaced bottom walls of the two cup-shaped members and within the passageway 50 is a generally elongated U-shaped wall 52 which forms a passageway 53. The open end of passageway 53 communicates with the side wall passageway 48. A discharge spout 54 communicates with the side wall passageway 48.

Extending from the bottom of the container is an internally threaded sleeve 56 for threaded engagement with the neck 12 of the bottle 10'. There is also a central boss 58 provided with a central bore 60 communicating with the passageway 53 in the bottom of the container. The bore 60 receives and anchors a pipe 34 extending into the container or bottle 10. The passageways 48, 50 and 53 form the heat exchanger of the unit.

The material in the bottle 10' passes through the pipe 34' into the passageway 53 and into and around the passageway 48 and is discharged through the spout 54. The cup-shaped container 42 is filled with hot water which in turn heats the aforesaid passageways and the material in the passageways so that when the material is discharged through spout 54 it is discharged in a heated state.

The devices shown herein are detachably secured to containers or squeeze type bottles of conventional type and the devices are reusable. In other words, after the contents of a bottle is exhausted it is readily detached from that bottle and applied to another filled bottle.

It is understood that while the invention shown herein is of a detachable character that same may be made as an integral part of the container within the purview of this invention.

It will be understood that various changes and modifications may he made from the foregoing without departing from the spirit and scope of the appended claims.

What is claimed is:
